Fitzpatrick said the gun held by William Wood Jr. likely jammed as he was about to shoot the other two people, as they were trying to leave the restaurant.

"By all rights, we should be discussing four homicides," Fitzpatrick said.

"They were executed," District Attorney William Fitzpatrick says of the two people shot and killed while leaving work after closing up at Chili's in DeWitt. The gun jammed, or Fitzpatrick said the two survivors would also have died, as William Wood Jr. intended. pic.twitter.com/d5DlMXLdpd

Wood, 32, was arraigned Sunday on two counts of first-degree murder and one count of robbery after he was picked up in Fulton. Fitzpatrick said questions remain as to how he got to Chili's and how he fled the scene.

Wood was a former employee and Fitzpatrick said he tried to disguise his appearance but was recognized by the victims. Wood was not believed to be disgruntled; rather, that the motive appeared to be robbery, Fitzpatrick said.
